2. DEFINITION : What is Glass ? Glass is one of the most important materials in usage and finds many practical applications in our daily lives and throughout the world. Generally, glass is characterised as a transparent solid material that can be used to make a variety of products in fields like architecture and design. If we stick to the definition of glass, then scientifically, it is defined as a non-crystalline amorphous solid that has the property of transparency, and is used for practical, technological and decorative purposes. What is glass made up of? Of all types of glass, silicate glass is the most common and widely used. This type of glass is based on the chemical compound silica, also known as silicon dioxide or quartz. Silica is most abundantly found in sand in the form of a mineral called quartz. While silica is the main constituent of glass, other chemical compounds such as sodium oxide, sodium carbonate, and lime or calcium oxide are added to it in order to yield glass of desirable properties such as the right melting point and viscosity. Out of all manufactured silicate glass, soda lime glass accounts for more than 90% production. It contains 75% silica, sodium dioxide, lime, magnesia or magnesium oxide, and alumina or aluminium oxide. Soda lime glass is the glass used in architectural and automotive applications.

3. I mportant properties of  glass? It is usually transparent It has a smooth surface It has a clear appearance It can reflect, refract and transmit light without scattering it Silicate glass can be poured, formed, extruded and molded into many shapes including flat sheets and complex designs It is brittle It is erosion-resistant, especially against the action of water Usually resistant to chemicals, and is also corrosion-resistant

4. Types of glass AUTOMOTIVE GLASS Automotive glass includes laminated and tempered glass applications in the form of vehicle components such as windshields, side windows, mirrors, headlight and tail-light glass, etc. Glass is an important component of vehicles since it provides structural integrity and also shields the occupants from external elements on the road. Laminated Windshields Laminated glass is a type of glass which consists of two sheets of glass with a plastic interlayer separating them. Thus, laminated glass is quite impact resistant, and in the event of breakage its glass pieces remain stuck to the plastic interlayer, thus protecting the passengers from injury. For this reason, automotive laminated glass is used in windshields. Value-Added Glass Products Automotive glass also includes other applications and accessories in vehicles such as defogger glass, glass antenna, encapsulated glass, PET windshield, water-repellent glass, rain sensor windscreen, etc.

5. Types of glass Annealed Glass Annealed glass or float glass is the most basic form of manufactured glass that lacks the toughness or impact resistance of processed glass. Clear Glass Clear glass is a kind of float glass which offers extreme transparency and clarity. AIS Clear Float Glass is the highest quality clear glass with high precision flatness. Tinted Glass Tinted glass is annealed glass that has a coating or a film that imparts it colour and reduces its light transmission. AIS Tinted Glass is a body tinted glass which absorbs energy from solar radiation. Frosted Glass Frosted glass is a translucent glass made by the process of sandblasting or acid etching. Its pitted, rough surface gives it a foggy appearance, thus making it the perfect solution for privacy. AIS Krystal, India’s only branded Frosted Glass, obscures the view while allowing light to pass through it.

6. Types of glass Processed Glass Processed glass is a type of glass made by subjecting annealed or float glass to thermal or chemical treatment in order to change its properties. There are various processing techniques such as lamination, toughening, sandblasting, acid etching, lacquering, enamelling , glazing, etc. The two main types of processed glass are laminated glass and toughened/tempered glass. Laminated Glass Laminated glass is a type of security glass manufactured by sandwiching a layer of plastic such as PVB in between two sheets of glass. This insulator layer makes the glass impact resistant and sound resistant. Laminated glass, upon breakage, remains intact as the broken pieces stick to the interlayer. Tempered Glass Tempered glass or toughened glass is formed by heating annealed glass in order to develop opposite stresses on its surfaces. This makes toughened glass much stronger than regular glass. AIS Stronglas is a very high grade tempered glass that is several orders of magnitude stronger than ordinary glass. Fire-resistant Glass Fire-resistant glass, such as AIS Pyrobel , is a multi-laminated glass with an intumescent layer which can withstand extreme levels of heat, smokes and flames. Retrofitting glass This type of glass, such as AIS Renew, has a low-E interlayer and is applied above old windows in order to make them more energy efficient.

7. Types of glass SOLAR GLASS Solar glass is a type of glass that has applications in the solar energy manufacturing industry. Solar glass is used in various components such as solar minors, solar panels, solar cells, etc. in order to harness the energy of the sun. AIS Solar Glass deals in all these products in the Indian solar glass segment . ARCHITECTURAL GLASS Architectural glass includes special types of glass used for building design and construction applications such as windows and doors. This glass is tailor-made to provide specific functionalities to the space they are utilized in such as security, privacy, noise insulation, energy efficiency, aesthetics, pollution control, etc.

8. Applications of Glass in Buildings Residential & Commercial Buildings Residential   – Glass applications in home are based on creating a comfortable and safe living space. Thus, glass doors and windows are often used to cut down on heat and glare, filter out external noise, increase natural lighting, provide security, or improve the décor. Professional   – Glass applications in offices are based on creating a productive environment. Thus, facades, cabins, partitions, doors, windows, etc. are tailor-made to increase privacy, cut down noise, and increase the energy efficiency. Hospitality   – Glass applications in hotels are based on creating a relaxing and appealing aesthetic for guests. Healthcare   – Glass applications in hospitals are based on creating a comfortable, safe and peaceful ambience for patients while also upholding their privacy and insulating noise. Retail   – Glass applications in retail stores are based on creating an attractive and comfortable environment for customers both inside and outside the store. Interior & Exterior of Buildings Interior   – Doors, windows, partitions, shelves, cabinets, table-tops, panels, cubicles, blinds, staircases, etc. Exterior   – Spider glazing, balconies, swimming pool glazing, facades, external doors and windows, canopies, skylights, walkways, etc.

12. GLAZING Glazing, which derives from the Middle English for 'glass', is a part of a wall, made of glass. Glazing also describes the work done by a professional " glazier“However , three glass characteristics need to be understood to optimise a fenestration system: 1.U value 2.Shading coefficient and 3.Visual transmittance CURTAIN WALL STRUCTURAL GLAZING SPIDER GLAZING ON TENSION ROD SYSTEM SKY LIGHT SLIDING DOORS ALUMINIUM DOORS

13. CLADDING Cladding  is the application of one material over another to provide a skin or layer. In construction,  cladding  is used to provide a degree of thermal insulation and weather resistance, and to improve the appearance of buildings .

14. FAÇADE TESTING What is glass Façade testing? Glass façade testing is a process where in the façade is tested for its designed performance for Structural stability & leakage’s against air & water infiltration. Why Testing? To identify & rectify Improper design Improper fabrication Improper installation

15. FAÇADE TESTING Advantages of testing Assurances of performance of the glass façade as per design requirement Peace of mind on the functionality of the system Saving in time & money as few rectification on site after installation Leak proof building Increased life of the building Importance of testing These tests are a must & should be performed on every project as no two projects are similar & this helps the Project Manager to act proactively, thus save Valuable material in the form of modification, Valuable time & Valuable Money.

16. ADVANTAGES OF GLASS FACADES I t adds to the beauty and panache of a building. Since it can be made translucent or molded in different shapes, it can offer lot of flexibility to the architect in terms of usage in the building. Glass can transmit 75-80 percent of the natural light in both the directions, something which no other substitute does. Glass can transmit light without clouding or yellowing. Glass does not rust so it is better than iron and does not succumb to its surrounding environment conditions. Glass facades require low maintenance and a swift monthly cleaning may be enough most of the times. It reduces weight on the foundation of the building and makes the building lighter as compared to walls. Most glass types are abrasion resistant which means that it will not wear out when rubbed against another material.

17. DISADVANTAGES OF GLASS FACADES Glass facades cause a lot of glare which is a major disadvantage of glass. Glass absorbs heat. This means that it can act has a greenhouse and hence not suitable for countries with hot climate. Most glasses are not earthquake resistance and not suitable for countries that witness frequent earthquakes. A very expensive kind of treatment given to glass can make then earthquake resistant but such type of glass is not very affordable. Use of glass in a building may result in higher costs in making the building safe and secure because glass results in lot of transparency. Glass is a rigid and brittle material. This means it breaks easily when a sudden pressure is applied to it.
